A sail almost never fails in the middle. It fails where the sun reaches it, where it rubs the rig, and where the load concentrates. Protection is what decides whether that takes three seasons or ten.
UV cover
The single most effective thing you can add to a furling sail.
A furling headsail spends most of its life rolled up in direct sunlight, and ultraviolet is what destroys both cloth and stitching over time. A cover on the exposed leech and foot takes that exposure instead.
Acrylic cover
The durable choice. Heavier and more expensive, and the best UV life available. Standard for boats left rigged year-round in strong sun.
UV-treated woven cover
Lighter and cheaper, and it furls more neatly. Shorter life than acrylic, which is the trade.
Which side matters, and it is not obvious. The cover goes on whichever side ends up outermost when the sail is furled, and that depends on your furler's direction. Getting it wrong makes the cover useless. We settle it from your photographs rather than assuming — see Measuring and Photographing.
Worth having on: roller-furling genoas and jibs, and furling Code Zeros.
Chafe protection
Anywhere the sail touches the rig, it wears. Patches take the abrasion instead of the cloth, and they are far cheaper than the repair they prevent.
| Patch | Where it goes | Worth it when |
|---|---|---|
| Spreader patches | Where the leech crosses the spreader ends | Almost always on a main; positions come from your rig |
| Stanchion patches | Along the foot of a genoa | Deck-swept headsails on boats with tall stanchions |
| Lazy jack patches | Where the lines bear on the sail | Any main dropped into a cradle or stack pack |
| Chafe strips | Along edges that bear on a boom or guardrail | Offshore and long-distance use |
Spreader patch position is not standard — it is set from your rig geometry, because a patch in the wrong place protects nothing.
Edge and corner reinforcement
Corners and edges are reinforced as part of the completed sail specification. See How Our Sails Are Built for the shared principles. What you can add beyond the normal build is extra edge protection for sails that will see harder use than their size suggests.
Other options
- Leech line and foot line, for controlling flutter as the sail ages
- Draft stripes and telltales
- Sail bag or turtle
- Reef marks and identification
Why this is worth reading before you order. Chafe and UV damage are wear, not manufacturing defects, so they fall outside warranty everywhere in the trade — ours included. That is precisely why the protection package matters: a spreader patch costs very little beside the repair it prevents, and the decision is easiest to make before the sail is built rather than after.
